I am not aware of anywhere in the Bible that abortion is prohibited, but again, the Bible is not an exhaustive list of "do's and don'ts", so much as it is an illustration of all the foibles human beings fall into, the various strategies the devised to address those foibles, and the attendant results of those strategies.
My experience is that Christians themselves have mixed opinions.
With that said, we can cherry pick various parts of scripture to support either pro/con positions. "All things are permissible, not all things are beneficial". (1 Corinthians 10:23).
My exposure to the anti-abortion argument is that it hinges on life beginning at conception, and the sanctity of life. For me (and I am Christian), that is a weak position. It assumes the life of the unborn pre-empts that of the already living. It leads to some pretty gnarly ethical issues.... do couples who have 20-30 embryos frozen in fertility clinics have the right to discard unused embryos? Or is conception in a test tube somehow qualitatively different than conception in a uterus? Does society have the right to "kidnap" the unused embryo's stored in clinics, and find a womb for them? If not enough wombs available, does society have the right to demand that females be pressed into service gestating them, though unwilling? Or do we, the child bearing, have the right to demand the childless not take advantage of fertility techniques? (there are literally hundreds of thousands frozen embryo's in clinics right now-unused ones are discarded when the biological parents discretion I believe).
Second, we take innocent life all the time, and justify that action on the basis of self protection. We war, we execute, we deny access to many based on "qualifications" of self-support, past health status, etc. We in fact "prioritize" who the worthy are when it comes to providing the goods of society.
And if we look at what defines "life" from the opposite end of the spectrum, when an individual is incapacitated, when they cannot communicate with others, when they cannot interact with their surroundings, when they cannot function or survive without a host of machines, we declare them brain dead and "harvest" their organs (I find that terminology repugnant myself). The very definition we use to declare "brain dead", can equally be used to define the state of the fetus. The only difference to me is that the fetus has the "potential" , if uninterrupted, for a full life.
And at last count, there were 117K+ children in foster care in the U.S. waiting for adoption. Nope, abortion is not an issue for this Christian. Sorry I am so long winded..... but as a 65 year old woman, I lived pre "Roe vs Wade" , post "Roe vs Wade".... abortion has always been available. The only difference now is "safe" abortion means the woman, instead of dying with her fetus, may go on to have a future family, and future children.
